Dredge conversion from jet flare to crash box...
Let me restate, as I truly respect your opinion HJ, and hoped you would respond.

That is my only reason for wanting the crash box.

Some dredge basics
In any dredge, you will have 2 types of suction devices; either a suction nozzle or a power jet. A suction nozzle only works with higher pressure pumps. The recommendation is a minimum of 140-foot head lift for a suction nozzle. A power jet can run at a slightly lower head lift at a 130 foot, however it does require higher volumes.

Keene Dredge Suction Nozzles
